Sub-Zero refrigerators are in a class of their own, with features like optimum temperatures and maximum storage. But one of the top amenities of these necessary appliances is the built-in water filter. With this, you and your family can access clean drinking water 24/7, saving you a lot of additional costs!
However, it’s important to change the Sub-Zero refrigerator water filter regularly to avoid any unwanted particles and contaminants in your drinking water. Usually, you need to change it every six months, but how do you replace your water filter?
Before you figure out how to change it, you have to know which type of Sub-Zero fridge you own. Refer to your owner’s manual to find out which model you have.
Once you have sourced this information, the good news is that this is a quick and straightforward process. Read on to learn how to replace your Sub-Zero refrigerator water filter, including both push-in and twist-in water filter types.
How to Replace a Sub-Zero Push-In Water Filter
Push-in filters are located on the bottom of the refrigerator. To access the filter, pull out the grille assembly’s bottom portion and gently tilt the grille frame upward. Once you’ve located it, complete the following steps to insert your replacement:
- Remove the previous water filter by pushing the cartridge in and then pulling the cartridge out.
- Remove the new filter’s plastic cap.
- Align the filter cartridge to the locking tabs; push in the cartridge until it clicks into place.
- Pull on the newly installed cartridge to make sure it is securely in place.
- To rest the filter monitor, hold the filter rest button for 5 seconds.
Once you have installed the filter, you will have to clear the system. Do this by throwing out the first two containers of ice and discarding the first two minute’s worth of filtered water.
How to Replace a Sub-Zero Twist-In Water Filter
If your model has a twist-in water filter, it will most likely be located in the front of the fridge just behind the water filter panel. However, based on the Sub-Zero refrigerator model, your twist-in filter may be found behind the grille or on the top of the interior door.
Replacing this kind of filter is a simple process. Just complete the following steps to have purified water again:
- Remove the previous filter by twisting it counter-clockwise.
- Remove the new filter cartridge from its packaging, and take off the new filter’s plastic cap.
- Put the newer filter in the filter compartment, and rotate counterclockwise until the filter is seated and secured.
- Your fridge may automatically reset, but if not, press the Reset the Filter icon for approximately five seconds.
Like push-in water filters, changing twist-in filters requires you to flush out the water system and air in the line. All you have to do is dispose of the first bucket-worth of ice and five or six glasses of newly filtered water.
Signs You Need to Replace Your Refrigerator Water Filter
Not every Sub-Zero model needs a water filter replacement at the same time. To know for sure, it is best to refer to your owner’s manual. There are some signs you can look out for to determine whether or not you should change the filter. If you notice any of the following changes, it’s time to update your filter:
- The dispenser appears to have decreased water pressure.
- The refrigerator’s drinking water has an odd taste.
- Ice from the ice maker also has an unpleasant taste.
Sub-Zero Water Filter FAQs
If you still have some questions about when or how to replace your water filter, take a look at these frequently asked questions. You may find what you’re looking for!
Why Replace Your Water Filter?
Having a clean Sub-Zero refrigerator water filter is necessary for it to provide the best water at all times. The purpose of your filter is to purify your drinking water, but an old filter can’t protect against minerals and pollutants.
That’s why regularly changing your water filter is so important. How often you need to replace it depends on the model you have, which you can find in your owner’s manual.
Where to Buy New Filters?
There are a couple of options when it comes to buying a replacement filter. You can purchase them directly from Sub-Zero through their accessory store or through a certified parts dealer.
What Should I Do With the Old Filter?
Although water-filters are safe to throw in the trash, Sub-Zero doesn’t recommend this. Instead, find a local recycling center that accepts water filters. For the US, visit Earth911.com to locate one near you and see if they accept water filters.
Do Sub-Zero Water Filters Expire?
Sub-Zero filters do not have an expiration date, but they do recommend you place the filters in a cool, dry space. Keeping your filters in a cold, damp area can affect the performance of your water filter.
How Long Should Water Filters Last?
The average lifespan is about 1 year, but many different factors can affect the lifespan of your filter.
What Affects the Filter’s Lifespan?
Some of the things that can affect the filter’s life span include water usage, water pressure, and the time elapsed since installing the previous filter.
What if the Water Filter is Stuck?
Changing a filter is easy, but not if it’s stuck. This is a common problem that is caused by sediment or mineral deposit buildup. If the filter is improperly installed, this can also create the issue. Using a jar opener for a better grip is typically all it takes to get the filter unstuck.
If this doesn’t work, contact an appliance repair service to schedule a troubleshooting appointment for repair.
